Abstract

Purpose This paper aims to propose Hidden Converter (H-Converter) combined with dual port 3Ø inverter for energy storage application to produce wide range of voltage. Some of the application required wide range of voltages, but problem from E-chopper is either boost or buck mode of operations, both modes are not possible. To overcome this drawback, H-Converter is combined with dual port 3Ø inverter controlled by carrier-based pulse width modulation (CB-PWM) technique is added with zero sequence injection. Design/methodology/approach Hidden converter is a bidirectional DC-DC chopper used to convert fixed DC to variable DC and vice versa in both buck and boost modes of operations. Dual port inverter is combined with hidden DC-DC converter can produce wide range of voltages. Findings The bidirectional DC-AC converter requires less power for processing and consumes less power losses by using modest carrier built- pulse width modulation scheme through proposed zero structure addition. Originality/value By using this proposed strategy H-Converter can produce wide range of voltage in both the sides and mostly power is processed in the 3Ø inverter with a one stage conversion with less power loss. As a result, with one stage power conversion has more efficiency because of less power loss. This proposed converter has designed by analysis, and the real time result is tested in an experiment.

使用H转换器的集成DC-AC和AC-DC转换器，适用于宽范围电压应用

本文旨在提出与双端口3Ø逆变器相结合的隐式变换器(H-Converter)用于储能应用，以产生宽范围的电压。一些应用需要宽范围的电压，但问题从e斩波器是升压或降压模式的操作，两种模式都是不可能的。为了克服这一缺点，将H-Converter与双端口3Ø逆变器相结合，该逆变器采用基于载波的脉宽调制(CB-PWM)技术控制，并增加了零序列注入。隐藏转换器是一种双向DC-DC斩波器，用于在降压和升压操作模式下将固定DC转换为可变DC，反之亦然。双端口逆变器与隐式DC-DC变换器相结合，可以产生宽范围的电压。通过提出的零结构加法，采用适度载波内建脉宽调制方案，降低了双向DC-AC变换器的处理功耗和功耗损耗。独创性/价值采用这种策略，h变换器可以在两侧产生宽范围的电压，并且大部分功率在3Ø逆变器中处理，具有一级转换，功耗更小。因此，一级功率转换由于功率损耗小而具有更高的效率。通过分析设计了该变换器，并通过实验验证了其实时性。
